ADR1399KEZ (ceramic LCC package) standard voltage reference

[Rax]

I just recalled I've acquired one the these "ultra-stable" voltage references a while back, and found it at the bottom of my parts bin. They seem to be pretty good, not quite in the LTZ1000 class, so probably not royalty but next of kin.

Is there anyone that has created a PCB or some kit for a 7V or 10V reference based upon this part? I have a sense I looked this up a while back, but can't find any records on that work.

Let me please ask you, why is it that you are opening one thread after the other, if there is a search function implemented in the forum that reveals that most of topics you are asking for have already been discussed and you find the answer to your question just there? Is it poor lazyness to use the search function or what is it?

The LCC package would ideally be mounted on something like an extra flex PCB to get better thermal isolation and less stress from the PCB. The reference is heated and this can cause extra stress an a normal PCB. An alternative, especially for a 1 off solution would be dead bug mounting with thin wires - ideally something with lower thermal conductivity than copper or really thin strands.
The circuit around the ADR1399 is relatively simple and could use a prototype PCB.  An OP07 should be sufficient for the amplifier and if really 10 V is the target, I would consider a TDP resistor array (e.g. 2 K or 5 K) as  1+2P : 3+2P.   Otherwise designs for a LM399 are not that different and could be still usable.

True, and duly noted! In fact, in my hours of research, I've concluded using Google to parse through EEVBlog is more efficient and returns better results than using the forum's own search function.

branadic, Kosmic, iMo - while willing to accept this particular thread was a little complacent to initiate (in the many other communities I'm in, given my contributions, I allow myself to ask for help from the given community as I would from friends, and so at times ask for a hint, or a nudge, or a reminder).

But as I feel branadic's point pertained to other threads I recently initiated, I'll take exception to his criticism. For instance, see  https://www.eevblog.com/forum/metrology/agilent-keysight-03458-66509-dcv-reference-pca-for-3458a/msg5195181/#msg5195181, and hopefully reassess whether you feel that my work is lazy.

On this community in particular, I think exceptional work gets swamped in a myriad of posts that no one not being part of the original chain can ever untangle. My contribution here is organizing that ("wiki" it). If the original work is valuable, contributions such as mine are in respect of it.

After this note - and the linked thread above - if you still feel my contributions here are lazy, I can't imagine there's anything I can do about that. But if you don't, I'd urge you to withhold similar judgements in future occasions. Just skip those threads, if upon honest self-assessment, you feel you have no constructive contributions to make.

I have been working on a 10V reference for ADR1399KHZ recently, and its performance is very good. I used the voltage following circuit from the official circuit and then amplified it to 10V
